In traditional studies on North Korea, conservative media in South Korea generally report and have an attitude toward anti-North Korea. It is a similar context as South Korea's conservatives view the U.S. and Japan more closely and positively than North Korea. This study is about how the reporting frames and information sources on North Korean science and technology in South Korea's conservative and progressive media differ and show trends. As a result of analyzing the reporting frame on North Korean science and technology by conservative and progressive media, progressive media showed similar trends or slightly positive responses to North Korean science and technology. But the reanalyzed result after dividing it into conservative and progressive governments, the opposite result came out. In the conservative government, the progressive media dealt with very positive aspects of North Korea's science and technology, and in the progressive government, there was a clear tendency to report negative rather than positive. What can be inferred from this is that the progressive media of South Korea had at least quite different directions of the progressive government in dealing with North Korean science and technology, but rather close to anti-North Korea. It is difficult to reach a hasty conclusion because this study has not dealt with all the press and only 10 years after the Kim Jong-Un regime. Nevertheless, this study may provide implications in that it is the first study to analyze how South Korean conservative and progressive media frame North Korean science and technology.

This study stereotyped the media on the basis of ideological inclinations and media types and explored the news coverage through word analysis, network analysis, and frame analysis. There was no difference between conservative media and progressive media in terms of the amount of news. The conservative mainstream media considered the THAAD rumor as an unnecessary misunderstanding and a rumor based conflict of the south-south. The progressive mainstream media mentioned much about Hwang Gyoan, external influences, and lies and highlighted the government's opinion that there was external influence that spread a vicious rumor. Conservative media mentioned on the bringing about social disturbance and in case of progressive media mentioned social disturbance, and progressive media mentioned the responsibility of government and the attitude of conservative media about the diffusion of the rumor. In conclusion the press framed the THAAD rumor on the basis of their ideological inclinations instead of the role of journalist.

The most noticeable aspect of progressive streaming is the media playback during its download through TCP to avoid a lengthy wait for a content to finish downloading. By employing TCP, it is usually possible to detect lost packets by using the checksum and sequence numbering functions of TCP Thereafter, we can recover the lost packets by the retransmission function of TCP. However, there must remain enough amount of media data in the recipient buffer in order to guarantee seamless media playback even during retransmission. In this paper, we propose an efficient algorithm for determining the initial buffering time before start of playback to guarantee seamless playback during retransmission considering the probability of client buffer under-flow. The effectiveness of the proposed algorithm will be proved through extensive simulation results.

This paper argues that media criticism should be reestablished as an academic movement leading to the maintenance and maturity of democracy. Korean democracy has been withdrawn both procedurally and practically. However, the Korean media do not properly monitor democratic retreat. The purpose of journalism is to provide people with the information they need to be free and self-governed, and the public sphere is a condition of deliberative democracy. This paper proposed three practical strategies for media criticism. First, it is the overcoming of the conservative-progressive frame. It is important to look at what kind of media is responsible for democratic retreat. Second, media criticism should be expanded on workers and capitalists. Korea's labor relations are as distorted as the public sphere. Korean journalism did not set agenda for labor relations. Most reports were 'capitalist bias'. Finally, Media criticism should be the empowerment of the people who are the sovereigns of the media.

The candle rally against the import of American beef which lasted for a long time was full of various types of social movement. That is, new media including mobile phone, Internet, Internet cafes played an important role in mobilizing people around the rally. Thus, this research focuses on the meaning and effect of these kinds of movement. In particular, it analyzed the possibility of real time broadcasting through the Internet as civic journalism, which received much attention in the rally. For this, this research used case study and interview as main research method. Case study focused on Internet cafes based on the media coverage of the rally. Interviews were conducted with workers at OhmyTV, Color TV, and 615TV. These workers at progressive media emphasized on the scene coverage as the advantage of real time delivery. Transmitting many citizens' voices was another advantage. It is expected that personal media and progressive media which try to show the scent as it is will play an important role in the future journalism with the expansion of Wibro.

We investigated the frames represented in the news media coverage in Korean daily newspapers during dismissal procedure of the director-general of the public service broadcaster, KBS. We analyzed 470 newspaper stories in the period surrounding the dismissal. The use of news frames in newspapers depended on the disposition of outlets, conservative or progressive. Conservative newspapers, ChoSun and DongA, described the dismissal of the director -general with a generally favorable or supportive view, but progressive outlets, Hankyoreh and KyeongHyang, reported more and non-favorable for the issue. Our results showed that conservative newspapers more often used episodic and cause for dismissal frame in the presentation of news, whereas progressive more often used thematic and media independence frames. Main frames commonly used in the news are the cause for dismissal, conflict, media independence, and regime maintenance, respectively, which are formed by 9 minor news frames. Conservative newspapers concentered on the cause attribution; management responsibility, conflicts, and dismissal procedures, but progressive focused on media independence and dismissal procedures. All newspapers selectively quoted groups, institutions and actors to enhance their messages and frames. Finally, there was significant difference between stories in each newspapers and the court's ruling for the dismissal.

Based on the quincunx sub-sampling grid, the New Interleaved Hierarchical INTerpolation (NIHINT) method is recognized as a superior pyramid data structure for the lossless and progressive coding of natural images. In this paper, we propose a new image interpolation algorithm, Edge Adaptive Hierarchical INTerpolation (EAHINT), for a further reduction in the entropy of interpolation errors. We compute the local variance of the causal context to model the strength of a local edge around a target pixel and then apply three statistical decision rules to classify the local edge into a strong edge, a weak edge, or a medium edge. According to these local edge types, we apply an interpolation method to the target pixel using a one-directional interpolator for a strong edge, a multi-directional adaptive weighting interpolator for a medium edge, or a non-directional static weighting linear interpolator for a weak edge. Experimental results show that the proposed algorithm achieves a better compression bit rate than the NIHINT method for lossless image coding. It is shown that the compression bit rate is much better for images that are rich in directional edges and textures. Our algorithm also shows better rate-distortion performance and visual quality for progressive image transmission.

Recently, Hou and others introduced a (2, n) block-based progressive visual cryptographic scheme (BPVCS) in which image blocks can be gradually recovered step by step. In Hou and others' (2, n)-BPVCS, a secret image is subdivided into n non-overlapping image blocks. When t ($2{\leq}t{\leq} n$) participants stack their shadow images, all the image blocks associated with these t participants will be recovered. However, Hou and others' scheme is only a simple 2-out-of-n case. In this paper, we discuss a general (k, n)-BPVCS for any k and n. Our main contribution is to give two constructions (Construction 1 and Construction 2) of this general (k, n)-BPVCS. Also, we theoretically prove that both constructions satisfy a threshold property and progressive recovery of the proposed (k, n)-BPVCS. For k = 2, Construction 1 is reduced to Hou and others' (2, n)-BPVCS.

This paper is studying about how things are showed the montage theory and mis-en-scene effect in the screen media, what the concrete project's cases and how those theories have been supported to the animation's effects and its development. Besides, 1 tried to describe the shown things in the animation area, what the montage theory and mis-en-scene effect had been imported and expressed based on the screen studies of representative genre in the visual media. The purpose of this thesis suggests to help the creative animation scenes by liberal understanding and acceptance about the montage theory and mis-en-scene effect for the future animation's progressive aspect. With the improvement, there this thesis's suggestions could help the creative and special effects of animation asa part of Screen Arts, and would be the part of the progressive factors in the animation area.
